本标准规定了确定旋转机械（如固定式燃气轮机、压缩机和其他固定式内燃机）进气过滤系统中所用空气滤芯耐水性能的一般要求、试验装置和设备、鉴定、试验材料、试验程序和报告

This document specifies general test requirements, the test rig and equipment, the test materials and the test procedure and report for determining water endurance performance of air filter elements used in air intake filter systems for rotary machinery such as stationary gas turbines, compressors and other stationary internal combustion engines. The test evaluates water endurance performance of air filter elements under laboratory conditions. The performance results obtained in accordance with this document cannot be quantitatively applied (by themselves) to predict performance in service with regard to water endurance and lifetime.
